Using static libraries with CocoaPods 1.5 no such module at import

Question

With CocoaPods 1.5 released I am trying to migrate from having 10-15 dynamic pods in my projects to having them as static libraries instead, with the goal of speeding up my app

Answer 1

In most cases for a small project it will be enough to add use_modular_headers! instead of the removed import_frameworks!.

Alternatively you can try adding :modular_headers => true after each pod declaration of a "missing" module:

pod 'Firebase/Auth' :modular_headers => true
pod 'Firebase/Database' :modular_headers => true
pod 'Firebase/Storage' :modular_headers => true
pod 'Firebase/DynamicLinks' :modular_headers => true

However, a bigger project might contain modules that just don't want to be static, with or without modular headers. One good example is Facebook SDK. For this case there is a cool addition here, which allows to specify which modules you want to leave dynamic.

Here's an example podfile, where all libs will be static except the ones, listed in the dynamic_frameworks array:

platform :ios, deployment_target: '9.3'

inhibit_all_warnings!

# Import CocoaPods sources
source 'https://github.com/CocoaPods/Specs.git'
use_frameworks!
dynamic_frameworks = ['Bolts', 'FBSDKCoreKit', 'FBSDKLoginKit', 'FBSDKShareKit']

# make all the other frameworks into static frameworks by overriding the static_framework? function to return true
pre_install do |installer|
    installer.pod_targets.each do |pod|
        if !dynamic_frameworks.include?(pod.name)
            puts "Overriding the static_framework? method for #{pod.name}"
            def pod.static_framework?;
                true
            end
        end
    end
end

target 'MyApp' do
pod 'SwiftLint'
pod 'Firebase/Auth'
pod 'Firebase/Database'
pod 'Firebase/Storage'
pod 'Firebase/DynamicLinks'
pod 'FBSDKCoreKit', '~> 4.33.0'
pod 'FBSDKLoginKit', '~> 4.33.0'
pod 'FBSDKShareKit', '~> 4.33.0'

end
